I Just Didn't Do It (2007) (Guest: Naoko Akimoto) (episode 43)

Jonathan Hafetz

This episode examines I Just Didn’t Do It, a 2007 Japanese film written and directed by Masayuki Suo. In the film, 26-year-old Teppei Kaneko (played by Ryo Kase) is traveling to a job interview on a packed Tokyo commuter train when a 15-year-old school girl, who was standing in front of him on the train and whom Kaneko hardly noticed, wrongly accuses him of groping (chikan). Kaneko is  arrested. He is advised by a lawyer to plead guilty and pay a small fine, after which he will be freed. But Kaneko maintains his innocence and decides to fight the case, even though he is told that nearly everyone who takes their case to trial in Japan is convicted. The film then documents Kaneko’s nightmare odyssey through the Japanese criminal justice system, where he is detained for months and ultimately convicted despite significant problems with the prosecution's case. I Just Didn’t Do It provides important insights into the Japanese criminal justice system and a critique of how it operates, including its treatment of the presumption of innocence.
